Cheat Sheet
- Understand the difference between symmetric and asymmetric encryption - Symmetric encryption uses a single key for both locking and unlocking data, which makes it super speedy but requires a secret handshake to exchange the key. Asymmetric encryption splits the magic into a public key for locks and a private key for unlocks, letting you share secrets without exposing the vault combination. Together they form the dynamic duo keeping our digital world safe! Dive into the basics cryptography101.org
- Familiarize yourself with common symmetric encryption algorithms - AES (Advanced Encryption Standard) is like the gold standard of encryption - fast, strong, and trusted worldwide - while DES (Data Encryption Standard) laid the groundwork before AES took center stage. Understanding how these algorithms shuffle and substitute bits helps you appreciate the art of scrambling data. Experimenting with simple code examples can turn these abstract concepts into "aha!" moments. Explore AES & DES cryptography101.org
- Learn about popular asymmetric encryption algorithms - RSA (Rivest - Shamir - Adleman) relies on the math magic of large prime numbers, making it a rock-solid choice for passwords and digital signatures. ECC (Elliptic Curve Cryptography) uses curves instead of huge primes, offering similar security with smaller keys - think of it as encryption on a diet! Both keep your chat apps, emails, and online banking locked down. Meet RSA & ECC cryptography101.org
- Grasp the concept of hashing and its role in data integrity - Hash functions act like digital fingerprint machines, turning any input - big or small - into a fixed-size string of characters. Even a tiny tweak in the original data creates a completely different fingerprint, helping you detect sneaky tampering. Hashes power everything from password storage to blockchain chains!

- Understand the purpose and function of digital signatures - Digital signatures use your private key to "sign" a message, guaranteeing it came from you and hasn't been altered in transit. Recipients verify your signature with your public key, giving non-repudiation: you can't deny sending it! This is the cyber equivalent of signing for a package.

- Explore key management and distribution techniques - Secure key management is like a treasure map: if it falls into the wrong hands, your loot (data) is toast. It covers safe key generation, sharing, storage, rotation, and destruction - no loose ends allowed. Mastering this keeps the vault firmly under lock and key. Key management 101 en.wikipedia.org
- Study block cipher modes of operation - Block ciphers split data into fixed-size blocks, but modes like ECB (Electronic Codebook) and CBC (Cipher Block Chaining) determine how those blocks dance together. ECB is simple but can leak patterns, while CBC mixes blocks like a baker kneading dough. Picking the right mode balances security and speed. Cipher modes explained en.wikipedia.org
- Learn about Kerckhoffs's principle in cryptography - Kerckhoffs's principle declares "the system should be secure even if everyone knows how it works, except the key." It's the ultimate trust fall: you only need faith in the secrecy of the key, not the secrecy of the algorithm. This mindset drives open-source crypto and peer review. Study the principle en.wikipedia.org
- Understand the role of cryptographic protocols - Protocols like SSL/TLS are the rulebooks for secure internet chats, encrypting data in transit so eavesdroppers hit a brick wall. They handle handshakes, keys, and checks that ensure your credit card number stays under wraps. Think of them as bouncers guarding the data party. Secure your comms cryptography101.org
- Recognize the core principles of cryptography - Confidentiality keeps prying eyes out, integrity ensures content stays true, authentication verifies who's who, and non-repudiation prevents denials. Together, these pillars form the fortress that protects messages, files, and entire networks. They're the ABCs of cyber defense! Meet the four pillars cryptography101.org
